Phantoms for performance assessment of optical coherence tomography systems [PDF]

, 2012
In this paper, we describe the procedures to make epoxy resin and agarose phantoms designed using Mie scattering calculations. The phantoms are constructed to be used in the estimation of point spread function (PSF) of an optical coherence tomography ...

Retinal neurovascular alterations are associated with optic radiation microstructure in adrenomyeloneuropathy: A susceptibility separation MRI study

VIEW, EarlyView.
In a cross‐sectional cohort of 104 participants, 7 T susceptibility separation MRI and diffusion imaging were combined with retinal imaging and visual evoked potentials to characterize visual pathway involvement in adrenomyeloneuropathy (AMN). Absolute diamagnetic susceptibility, a myelin‐associated measure, and fractional anisotropy (FA) showed ...

Acute macular neuroretinopathy associated with influenza vaccination with decreased flow at the deep capillary plexus on OCT angiography

American Journal of Ophthalmology Case Reports, 2018
Purpose: We report a case of acute macular neuroretinopathy (AMN) following routine annual inactivated influenza vaccination. Projection-resolved optical coherence tomography angiography (PR-OCTA) was used to analyze the retinal capillary flow within the

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

Acta Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Optical coherence tomography angiography in diabetic retinopathy. [PDF]

, 2023
There remain many unanswered questions on how to assess and treat the pathology and complications that arise from diabetic retinopathy (DR). Optical coherence tomography angiography (OCTA) is a novel and non-invasive three-dimensional imaging method that
